How Does a Fighter Lose His Chin?

[Kirkland Laing]

If you get punched in the head thousands of times over the course of a career's fighting and sparring then it's inevitably going to have a cumulative effect. Add on the physical drain of making the same weight over a period of years when you're getting naturally bigger, bad living habits away from the ring etc. and it's understandable that your general physical condition will deteriorate from what it once was. If you've had a few good batterings and a couple of sparkings over a bunch of tough fights then you're not going to be what you once were.

I think with Hatton particularly, the effect of getting KO'd by Mayweather affected him badly mentally. He went into that fight talking about how his chin could take all Tszyu had to give, so Mayweather would have nothing. He also made a point of him not being a proper welterweight (funny how things change ) when compared to Collazo. I think then getting KTFO by a guy who he thought he could walk through (not that he learned from that ) had an effect that he was getting buzzed off the slightest punch as a mental thing. I remember even Paulie managed to hit him with a punch that looked like it hurt him. So I wouldn't be surprised if there is a mental aspect to it.
